PUMP ROD ON WINDMILLS.

Application filed. October 26, 1923.

To all whom it may concern Be it known that I, ALBERT G. Eocene, a citizen of the United States, residing at Corsica, in the county of Douglas and State of South Dakota, have invented certain new and useful Improvements in Pump Rods on Windmills, of which the following is a specification.

This invention relates to a new and improved pump rod coupling for windmills and more particularly to the automatic releasable coupling designed to prevent breakage of various operating parts when the pump freezes.

A further object of the invention is to provide an automatic coupling of the above character which will. yieldingly permit movement of the pump rods away from each other prior to the actual disengaging or uncoupling operation, so as to compensate for the normal strain of the rods and to prevent uncoupling of the rods except when the pump rod is stuck fast.

Various other objects and advantages of my invention will become apparent during the continuance of the following description.

In the drawings.

Figure 1 is a view in front elevation showing my improved coupling in its preferred embodiment.

Figure 2 is a view in side elevation.

Figure 3 is a view in transverse cross sec tion taken on line 3-3 of Figure 1.

In describing my invention in detail, 10 and 11 designate the upper and lower pump rods, respectively, rod 11 being a part of the ordinary pump. At its lower end rod 10 carries a metallic socket 12 which is provided with oppositely projecting lugs 13 and a retaining lug 14, the latter being spaced from the end of rod 10, as clearly shown in Figure 1. It will be observed upon reference to Figure 3, lug 14 has a cen trally located cut out 15 and a flaring slot 16, open to the cut out for the purpose which will presently appear.

The member 17 is carried in space relation to lugs 13 and the lower end of rod 10, and is provided with upwardly projecting bolts 18 that pass through openings in the lug 13. Above the lugs 13, rods 18 carry coil springs 19 whose upper ends bear against washers 2O and the washers 20 in turn bear against nuts 21, which are adju t are mounted on the upper ends of rods 13.

Serial No. 670,914.

Thus it will be observed that the member 17 is held in yielding relation to pump rod 10 and that downward pressure on the member will be absorbed by spring 19.

The bracket 22 depends from member 17 at a substantially intermediate point and a carrying ring 23, in turn, depends from the bracket. The coupling member 24 has one end bent as at 25 to engage rin 23 while its other end is extended and slightly curved as at 26 so that it may be passed into the cut out 15 of lug ll by way of the flared opening 16.

The upper end of rod 11 also carries a metal socket 27 from which project lugs 28, the latter carrying a bracket 29 and a connecting ring 30, as clearly shown in Figure 1. While the socket 27 may be connected to the rod 11 in any suitable or desirable man ner, I have shown, for purposes of illustration, certain fastening members 31 and 32 for that purpose.

In making the connection between the rods 10 and 11 the free end of coupling member 24 is first passed through connecting ring 30, carried by bracket 29 and is then brought into the position shown in Figure 2 with its upper end within cut out 15 and lug 1 1. During the normal working oft-the different parts, springs 19 serve to establish a yieldable connection between the rods thus instu'ing the efficient operation of the parts. However, if rod 11 becomes fast, such as by being stuck or by the freezing of the water in the pump, continued upward pressure on rod 10 will cause springs 19 to become compressed and member 17 will become further spaced from lugs 13. This will draw the coupling member 14- upwardly and finally cause the end 26 to become disengaged from lug 14-, thereby automatically uncoupling the rods without breakage.

From the foregoing it is believed that the advantages and the essential. features of my invention will be readily understood, and, therefore, further detailed description is deemed unnecessary.

What is claimed is 1. A pump rod connection for Windmills consisting of two separated sections of a pump ro a pair of connecting rings, means for rigidly connecting one ring to one see-- tionof the pump rod, resil' leans for yieldably' connecting the rein the other section of. the pump red". a slotted retaining lug also carried by the said other sectionaanid a coupling member consisting of a bent rod hingedly connected to the said resiliently mounted ring and passed through the said rigidly mounted ring with its free end lodged in the slot of the said retaining lug.

2. A pump rod connection for Windmills including a pump rod fo'rmed'of two separated sections, a metallic socket engaged overeach of the adjacent ends of the said sect'ioris,'a bracket connected to the socket of one section, a ring carried by the said hrac et, a plate resiliently connected to the socket ofthe'other section, a ring carried by the said plate, a slotted retaining lug also carried by the socket of the said other section, and a coupling ineinber comprising a bent rod having one end h ngedly connected to the saidresiliently supported ring of the said other section and passed through the ring of the first-mentioned section with its free end lodged in the slot of the said rotaining lug.

3. A pump rod connection, for windmills consisting of upper and lower selmrated sections of a 1 un'ip'-rod, metallic sockets engaged over the adjacent ends of the said sections and respectively presenting out Wardly disposed lugs, the socket on the upper section having one of its lugs slotted to provide a retaining lug, a pair of connecting rings. non-yieldahle means connecting oneof the rings to the socket. lugs ofthe lower section, 'yieldahle means connecting the other H ring to the socket lugs of the upper section, and a bent rod passing through the ring or the lower section'witli one end liingedly con nected to the ring of the upper section and its other end releasahly engaged, in the slot of the said retaining lug.

In testimony whereof I aflix' my signature.
